BALlNG-PRESSA SPECIFICATION forming part of Letters Patent No. 373,617, dated November 22, 1887.

Application filed May 26, 1837. Serial No. 239,486. (No model.)

To all whom it may concern:

Be it known that I, ABIJAH SrMPsoN, of Lapeer, in the county of Lapeer and State of Michigan, have invented a new and Improved Baling-Press, of which the following is a full, clear, and exact description.

My invention relates to presses for baling hay, straw, cotton, or other material, and has for its object to provide a simple, inexpensive, and effective press of this character.

The invention consists in certain novel features of construction and combinations of parts of the balingpress, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of myimproved baling-press. Fig. 2 is a central vertical longitudinal sectional elevation thereof, taken on approved form providing a rear baling-box,

B, and space in front of said box in which the plunger 0 is operated to press hay or other material into bales. I show the press-case provided with a rear door, a, which,when

opened, allows discharge of the bale; but the press-case maybe made with a rearwardlytapering baling-box and an open rear end to discharge bales continuously after being tied through suitable slots, a, in the sides of the baling-box and in grooved head or spacing blocks placed in the box.

The press-case may be mounted upon a suitable wheeled truck, or may be otherwise set up for use in a barn or elsewhere.

The plunger 0 is operated by a heavy pit man, D, which is pivoted at (Z to the plunger and at its other end at d to a disk or drivewheel, E, which is fitted loosely upon an upright shaft, F, held in the press-frame and between the inner heavy upper and lower crossbars, 1 g, of a sweep, G, which is also pivoted on the shaft F, which passes through the crossbars 9. A pair of heavy pins, H H, fixed in the drive-wheel E, by their resistance against the forward edges of the sweep cross-bars 9, cause the plunger to be forced rearward in the press-case and allow the plunger to be forced outward again by the expansion of the material pressed in the baliug-box at each half-revo-' lution of thesweep,thus permitting one charge of material to be pressed as the sweep is drawn over toward either side of the press. Suitable spacing blocks or washers, f, will be used between the cross-bars g of the sweep and the upper and lower parts of the press case or frame to hold the sweep and drive-wheel in proper relation to the pitman and plunger. (See Figs. 2 and at of the drawings.)

At the side of the press-case next the feedopening I), through which the material to be pressed passes into the baling-box B, and preferably at the top of the case, as shown in the drawings, an auxiliary feed and press box, I, is built. This box I is open at the top, and opens also about at its center to the feed-opening 1) of the baling-box B, and with which opening the fixed front end, J, of the box I registers, while the rear end, 2', of the box, which lies on the main press-case A, serves as a brace or stay to the opposite sides of the box, which are slotted to receive side bars, K K, to which, within the box I, a head-block, L, is fixed, so as to travel backward and forward in the box.

A cross-bar, M, which is fixed to the forward ends of the opposite side guides, K K, of the head-block, is connected pivotally by a pitman, N, with the inner end or short arm, 0, of a lever, O, which is fnlcrumed on the main shaft F, and is extended forward to the outer end ofthe sweep G, to which it is coupled by a bolt, clip, or other device, and whereby, as the sweep is turned to operate the plunger 0 in the baling-box B, the head-block L will also be reciprocated in the feed-box I. A heavy block, P. grooved at the top to receive the cross-bar M as it moves forward, takes the force of the extreme or maximum lateral thrusts given the bar M by the pitinan and relieves the box I of side strains, to which it otherwise would be subjected. A spacing-block, 0, placed on the shaft F and between the lever 0 and the press-case A, holds the lever in proper relation to the pitman N and the crossbar M, connecting the pitman with the headblock. a v

The operation of the press is very simple and effective, and is as follows: We will suppose that the sweep G has been turned to one sideuntil the lever O, which is at the longitudinal center of the sweep, stands about in the position represented by the dotted line 6 in Fig. 1 of the drawings. At this time the plunger 0 will have been drawn fully back, and the upper auxiliary head-block, L, will have the position indicated. by the dotted lines in Fig'. 1, and the pin H in the drive-wheel E will rest against the cross-bars g of the sweep, as shown in Fig. 3 of the drawings. The charge ofhay which has been fed into the upper box, I,

and has been compressed therein by the headblock Lagainst the end Jof the box, will now be forced down into the baling-box B behind the drawn-back plunger 0 by any suitable device, and as the sweep is moved in the direction ofthe arrow 7 in Fig. 1 the cross-barsgof the sweep will bear on the pin H, and will force the plunger C rearward on its effective stroke as the sweep moves around toward the position indicated by the dotted lines 8 in Fig. 1. During the first part of the aforesaid movement of the sweep, and while the plunger 0 is pressing the material in the box B, the head-block L will be moved rearward in the feed-box I, and when the sweep-lever O is in line with the section-line l l in Fig. 1 the head-block will have been carried to its extreme rearward position, (shown in full lines in Figs. 1 and 2 of the drawings,) and during this rearward movement of the head-block, and while the feedopening b is closed by the top of the plunger 0, hay, straw, cotton, or other material to be baled will be fed in any way into the box I between its end J and the head-block L. As the sweep and lever G 0 continue their movement from the line 1 1 toward the line 8, the rearward pressing stroke of the plunger '0 will be continued,while the material in the box I will be pressed between the end wall, J of the box I and the forwardly-moving head-block L, and as the lever O nearly comes into line with the dotted line 8 the pivoted end (1' of the pitman D will pass the shaft F, and the expansion of the material just pressed by the plunger will cause the plunger 0 to rebound and swing the wheel E around quickly until its pin H" will strike the cross-bars g of the sweep. The position of the plunger 0 and head-block L is now as first described, and the charge of material in the box I, now fully pressed therein, will be forced down in rear of the drawn-back plunger 0, and as the sweep is started on its row 9 in Fig. lot the drawings, the sweep bars.

9 will bear against the pin H tov force the plunger 0 rearward on its effective stroke to. press the last charge of material into the bale being formed, While the head-block L will also be carriedv rearward to allow the next charge of material to be fed into the upper box, I, to be pressed therein, and afterward forced down when the plunger next rebounds, as will be understood from the aforesaid description, and the pin H will strike the sweep-bars g on the secondrebound of the plunger, and the parts will be in the positions first described and ready for the next efiective movement of the sweep from the line 6 toward the line 8, as will readily be understood.

By first compressing the charges of material by the auxiliary head-block or plunger L in the feed-box I am enabled to make the presscase A shorter and stronger for turning out bales of a given size and weight.

Retainers R (shown in Fig. 2 of the drawings) hold the successive pressed charges or batches of material against undue expansion in a well-known manner after each rebound of the plunger.

It is obvious that but one of the pins H may be used in the drive-wheel; but the two pins shown and above described are preferred in practice.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
